Robert Downey Jr. and Susan Downey have named their newborn daughter Avri Roel Downey.
The actor -- who already has a two-year-old son, Exton, with his wife of nine years -- is besotted with their baby girl, who he joked has inherited "a variety of Susan's traits" instead of his own "junk DNA."
Writing on his Facebook page Wednesday, the 49-year-old actor shared: "Yep...Avri Roel Downey joined the party at 3:22 a.m. on November 4th. She's 7 lbs even, spans 20 inches, and is accompanied by a variety of Susan's traits that have seemingly overwritten my 'junk DNA.'
"I'll post pics here and there when I'm not too busy staring..."
The 'Iron Man' star -- who also has a 21-year-old son, Indio, from a previous marriage -- admitted he can't stop taking pictures of Avri.
He wrote: "After 9 months of intensive development, Team Downey is pleased to announce our 2014 fall/winter project.
"Principal photography commenced 11-14 and will continue until she says, 'Dad! You are embarrassing me...I'm 30, this has gotta stop.' "
Downey Jr. previously confessed he was nervous about raising a daughter.
He said: "I've never had a daughter before, so I don't know what really prepares a dad. I'm asking around. But I did my part and now I'm just going to show up and do what I'm told."
